DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for detecting the room temperature of a petroleum stove of a vertical type.

[0002]

2. Description of the Related Art Generally, a room temperature detecting device of an oil stove is
A thermistor is mounted on the suction side of a convection fan that sends indoor air into the frame and converts it into warm air. The thermistor is configured by calculating means for converting the resistance value data of the thermistor to room temperature, and an LED lamp for displaying the calculation result.

[0003] The temperature data measured by the thermistor, which is a temperature variable resistance element, is converted into an actual temperature figure, and
In order to display with an ED lamp, a controller having full-scale calculation means is necessary. Such a controller can be easily added to a control unit using 100 V AC as a power supply by a fan heater or the like. It is actually used in fan heaters.

[0004] However, in a core vertical stove which uses a power source of a dry battery exclusively for ignition, if a controller having a thermistor, a calculating means and an LED display is operated while the stove is in use, the capacity of the power source becomes insufficient and the battery needs to be replaced frequently. This has to be done, which degrades practicality. For this reason, when using dry batteries as a power supply, use a temperature switch and an LED lamp, and turn on the LED lamp only when the room temperature reaches an abnormal temperature, to notify the operator of the abnormality or to automatically extinguish the fire with a solenoid. Was staying at.

[0005] For this reason, as a means for displaying the room temperature with a core up-down stove, the applicant has replaced a thermistor and a LED display using a power supply with a thermoseal whose display color changes depending on the temperature on the front of the frame. A proposal for attaching the thermo-seal to display the room temperature by the display color is disclosed in
No. 401.

[0006]

A core-up / down stove powered by a dry battery does not have a convection fan such as a fan heater, and cannot generate room airflow around a temperature sensor when detecting room temperature. For this reason, the temperature sensor cannot avoid the influence of the radiant heat of the burner, and even if the system detects the abnormal temperature of the room by the combination of the temperature switch and the LED lamp, the intention is to detect the room temperature, In some cases, a high temperature that is far from room temperature is detected, and there is a problem that the reliability of the detected temperature is poor.

In order to make the detected temperature equal to room temperature without blowing indoor air to the temperature sensor, generally, a plurality of heat shield plates for blocking radiant heat are provided between the burner and the temperature sensor. Things are going on.

[0008] Although the effect of radiant heat from the burner can be avoided by covering the temperature sensor with a heat shield, the convection of air deteriorates when the temperature sensor is covered with too many heat shields. Conversely, the heat builds up and eventually a temperature considerably higher than room temperature is detected.

Therefore, it is difficult to accurately detect the room temperature by simply covering the temperature sensor with a heat shield plate, and it is necessary to reduce the influence of radiant heat from the burner while easily causing air convection near the temperature sensor. There is.

At the end, an oil tank 6 provided with a core holding cylinder 5 on the upper surface is located, and a burner 7 is installed on the core holding cylinder 5, and the reflection between the back and side portions of the burner 7 and the frame 1. A plate 8 is provided,
In addition, a bottom reflector 9 having a burner opening 9a through which the upper part of the core holding cylinder 5 or the lower part of the burner 7 penetrates is provided, and the front edge of the reflector 8 and the bottom reflector 9 fixed to the lower part of the reflector 8 are framed. 1, a heat shield plate 10 for partitioning the space between the bottom reflector 9 and the table 3 below the core holding tube 5 is attached to the core vertical stove located at the periphery of the warming opening 2. A front bent portion 11 is provided at the front end of the front surface 1a so as to be opposed to the front surface 1a with an interval A therebetween. A near the front surface 1a or the front surface 1a of the frame 1 which forms an air flow path through A to the space B above the heat shield plate 10 and looks into the space C below the heat shield plate 10 below the bent portion 11. A temperature detector 12 for detecting a room temperature is attached to the apparatus.

A heat absorbing member 3a having a lower temperature than the front surface 1a is opposed to the front surface 1a of the frame body 1 near the temperature detector 12.
Is disposed in the space C below the heat shield plate 10, and the radiant heat radiated from the bottom reflector 9 irradiates the front surface 1 a of the frame 1 near the temperature detector 12 through the interval A, and the temperature detector 12 or The front surface 1a of the frame 1 on which the temperature detector 12 is mounted radiates and radiates heat toward the low-temperature heat absorbing member 3a, so that the influence of the burner combustion amount is reduced.

Further, when it is desired to display the room temperature even in the case of a stove having a vertical core, the temperature detector 12 arranged at a predetermined position on the front surface 1a of the frame 1 is attached to the outer surface of the front surface 1a of the frame 1. The thermo seal 13 serves as the temperature detector 12 and the temperature indicator 12a, so that the temperature can be displayed without burdening the power supply of the stove.

[0013]

The core vertical stove having the reflection plate 8 is provided with the heat generated from the burner 7 by the reflection plate 8 and the bottom reflection plate 9.
The parts that are radiating heat forward from the warming opening 2 of the frame 1, and which are particularly hot among the components of the oil stove, are the core holding cylinder 5 continuous from the burner 7 and the bottom reflector 9 that receives radiant heat.

In order to maintain a low temperature by using the heat shield plate 10, it is necessary to cut off radiant heat from these two parts. Specifically, the space between the bottom reflector 9 and the table 3 is partitioned. By providing the heat shield plate 10 below the core holding cylinder 5, the heat shield plate 10 divides the bottom reflector 9 and the table 3 into two upper and lower spaces B and C, and blocks the table 3 side. A lower temperature lower space C to which radiant heat does not directly reach is formed below the hot plate 10.

Further, a downwardly bent portion 11 is formed at the front end of the heat shield plate 10 to provide an interval A for forming an air flow path between the heat shield plate 10 and the front surface 1a of the frame body 1. Since the temperature detector 12 is provided at a position below the heat shield plate 10 and in the space C below the heat shield plate 10, the temperature detector 12 or the temperature detector 12 is provided.
Since the path through which the radiant heat reaches the front surface 1a to which is attached is limited by the interval A, the radiant heat only reaches from the bottom reflector 9 at a shallow angle.

For this reason, the temperature detector 12 or the front surface 1a to which the temperature detector 12 is attached is radiated and radiated toward the lower temperature lower space C while being cooled by the air rising at the interval A. The temperature at which the temperature becomes extremely close to room temperature can be detected for the first time with a core-vertical stove that does not use a convection fan or the like. In particular, if the heat absorbing member 3a having a lower temperature than the front surface 1a is disposed in the lower space C having a low temperature, the radiation and radiation of the temperature detector 12 or the front surface 1a on which the temperature detector 12 is mounted can be efficiently performed.

[0029]

As described above, the present invention makes it possible to accurately detect the room temperature even in the vertical stove. The conventional vertical stove does not have a function of forcibly cooling the temperature detector 12. When the temperature detector 12 is attached to the frame 1, it is difficult to accurately detect room temperature by radiant heat, and a complicated heat shielding structure is required. In the present invention, the heat shield plate 10 and the bent portion 11 at the front edge of the heat shield plate 10 make it difficult for radiant heat to reach the front surface 1 a of the frame 1 below the bent portion 11, thereby effectively dissipating heat by natural convection. By proposing a new structure that further reduces the effects of radiant heat, accurate room temperature detection has become possible for the first time with a core up-down stove without a convection fan.

That is, in the conventional core vertical stove, as a method of detecting the room temperature, a structure in which the temperature detector 12 blocks the radiant heat by a heat shielding structure or a method in which the temperature detector 12 is cooled by natural convection have been adopted. The lower space C of the heat shield plate 10 can be formed at a lower temperature than the temperature detector 12 and the front surface 1a of the frame 1 to which the temperature detector 12 is mounted, and the front surface 1a having the temperature detector 12 mounted in this space. The temperature detector 12 has a lower temperature closer to room temperature than when the temperature detector 12 is located between the bent portion 11 reaching the table 3 and the front plate 1a. The effect of being detectable has been obtained.

If only a low-temperature space can be formed by the heat shield plate 10 or the like, it is not necessary to arrange the heat shield plate 10 around the temperature detector 12 in a complicated manner as in the prior art. The structure for heat is very simple,
In addition, the temperature detector 12 can detect a temperature closer to room temperature than in the past by using an inexpensive structure.

In addition to forming a low-temperature space in the space C below the heat shield plate 10, if the low-temperature heat-absorbing member 3a is positively constructed from the table 3 or the like in this space, the temperature detector 12 or Radiation and radiation from the front surface 1a of the frame 1 near the temperature detector 12 work more effectively, and the temperature detector 12 can detect a temperature closer to room temperature.

The mounting position of the temperature detector 12 can be realized not at the position surrounded by the heat shield plate 10 in the frame 1 but at the position related to the front surface 1a of the frame 1. If the temperature detector 12 by the thermoseal 13 is attached to the outside of the thermo-seal 13, the thermoseal 13 can be directly viewed, and the current room temperature can be visually confirmed by the discoloration of the thermoseal 13. Detector 12
Since the LED display is activated by the signal of the above, the room temperature can be confirmed by the color change rather than the one that suddenly displays only the abnormal state,
The operator can easily operate the stove.
